How fast is fast to get on the hill?

[ianbbat]

I figure that in the first 15 seconds, most teams will blitz for the middle stack...and speed will be a great factor in doing so...

So how fast do you think \ anticipate being able to get to make an attack on the center stack?

We are estimating that within the first 5 seconds, we will have knocked down most of the boxes on top, but I am wondering how fast other people might be able to get to it.

I mean, it takes our robot a few seconds to fire it's stablization harpoon into the rafters, warm up it's jump jets, and engage it's shock cannon...

We plan on using a time travel device to have the stacks knocked over right when the match starts...no one will ever know!!

What about a team who may have a large arm to reach over the wall and knock over bins without ever having to move?!?!

Anyways....I'd say 1.5 seconds would be pretty fast...who knows how fast ours could go.

With our teams transmittion blueprints, they were estimating somewhere around 16 feet per second. I'm sure that some modifications will be made to change that along with certion factors.

we origonally wanted a 15ft/sec tranny... but then when you look at all the power you lose, and that no robot would really be able to go that fast and have someone contol it, and considering that the robot needs to make a 4' turn to get to the ramp, anything fast will just fall over if your tall. the sensors are also limited to how fast you can go, you would have to be dead reckoning and then if anything goes wrong the slightest bit you miss and take more time. getting up there fast is going to be harder than most teams think

we are just using a large 25 foot arm that can reach all over the field. skrew a drvie train.

*laughs* we anticipate 2 sec's at least to deploy our selves.

Wow, that is really ambitious, but if you guys can pull it off, then I fear you.

Well our robot is going to be around 7 ft/sec, but take into consideration that it is not a straight dash, getting to the boxes require turning and going at a speed much lower than the robot's potential speed =(

Not really... we are doing it in a way that requires very little turning... I'll let you think of how.

We are shooting for 6-6.5 F/PS. We were originally thinking 8-9 but we realized that if got into a pushing match, the motors would stall, breakers would trip etc.

shift gears, then you have no problem. Shifting the drill motors with a servo is very easy to do, and worth it even though you need to stop.

Theoretically 16ft/s would work well but think about how long it would take you to accelerate. When they ran the numbers for our tranny, I think they dropped the top speed in order to accelerate faster.

Personaly I feel that competitive teams will hit the wall in <7 seconds. On the other hand an arm or any "long shot" device could knock it down in <5.

[Cory]

I see competitive teams hitting the wall in 3-5 sec. Oh yeah, ever see kingman last year? hit the goals in 1-2 sec @ like 18 fps. They had incredible acceleration. Biggest disadvantage I see is probably not being able to turn due to friction at such high speeds. We went at around 13-14 fps last year, and turning at full speed was impossible.

With a front dually, rear swivel caster design, we aren't "Trapt" with the confines of not being able to turn on a dime, yet we achieve an amazing 16.5 fps on level ground, and should achieve over 13 fps over the ramp. We're light, and heavy on traction. Pun!

It's all on how many motors you use and how you gear it....

Pair up the CIM and Drill motors....use reduction from the CIMs to the drill running on high, gets some good speed....with quite a bit of torque....

There are similar match-ups, this is just one I know, fairly easy to do too.

[SpaceOsc]

its amazing how many different ways there are to knock down the boxes that dont involve wheels... of course this is a creative and most difficult task to pull off... im guessing most teams will have speed and depend on it for there control of the center stacks.... but i wanna see the teams that will use arms the center stack....

of course no team wants to tip there hand and show the rest of the world wuts up there selves but i really wanna know


Pushing

Moving walls

Large Over Extending Arms

Time travel

wut other ways of getting the stack have teams developed?
